Answer:
18 liters
Step-by-step explanation:
We can use ratios to solve
12 liters x liters
----------- = -----------
2 days 3 days
Using cross products
12 *3 = 2x
36 =2x
Divide by 2
36/2 = 2x/2
18 =x
18 liters
Use the diagram above. Is AB congruent to DE? To find AC in problem 3, suppose you subtract -2 from 5. do you get the same result? Why?
Answer:
(a) Segments AB and De are not congruent since their lengths are not equal.
(b) Yes, you get the same result. In both cases you must take the absolute value of the difference of the coordinates giving you the same result no matter in which order you subtract the coordinates of the points.
Step-by-step explanation:
(a)
To find the distance between any two points on the number line, take the absolute value of the difference of the coordinates of the points.
The coordinate of point P is p. The coordinate of point Q is q. PQ or QP, the distance between points P and Q, is:
PQ = QP = |p - q| = |q - p|
It does not make a difference in which order you find the diffeence of the coordinates.
Look at points A and B.
Point A has coordinate -2.
Point B has coordinate 3.
AB = |-2 - 3| = |-5| = 5
Now look at points D and E.
Point D has coordinate 10.
Point E has coordinate 14.
DE = |10 - 14| = |-4| = 4
AB = 5; DE = 4
Answer: The lengths of segments AB and DE are not equal, so the segments are not congruent.
(b)
The coordinate of point A is -2.
The coordinate of point C is 5.
AC = |-2 - 5| = |-7| = 7
If you subtract -2 from 5, and then take the absolute value, you get:
AC = |5 - (-2)| = |5 + 2| = |7| = 7
Again you get 7. The order in which you subtract the coordinates of the points does not affect the result since you take the absolute value of the difference in both cases.
AC =

You owe $25 on your credit card. You make a $5 payment and then
purchase $8 worth of clothes at Dillards. What is the integer that
represents the balance owed on the credit card?
Answer:
$12
Step-by-step explanation:
$25 on credit card - $5 payment - $8 clothes = what's left on the card
25 - 5 = 20
20 - 8 = 12
there's $12 dollars left on that credit of yours
find the missing value of X.
9514 1404 393
Answer:
x = 72
Step-by-step explanation:
The sum of interior angles of a pentagon is (5-2)(180°) = 3·180°. The sum of the two right angles is 180°, so we can write the equation ...
180° +2x° +x° +2x° = 3·180°
5x = 2·180 = 360 . . . . divide by °, subtract 180
x = 360/5 = 72 . . . . . . divide by 5
The value of x is 72.

A Sand dune stands 5 feet above sea level. the hill is eroding at a rate of 1 foot per 20 years. let y represent the height of the sand dune after x years. which equation represents the situation
Answer:
5 - (1 + 20) = yx
Step-by-step explanation:
So if 5ft is the original height, we would need to distribute that to decrease in the following years. That is where the 5 - comes from. Next we know that is it is eroding 1 foot in 20 years so that is 5- (1+20) You HAVE to distribute that and not add. Then it equals y the height of the dune in x, the years. Honestly 5 feet above sea level is kinda puny for a sand dune ;P.
Consider the following Expression.
-3(y+3)=2y+3
What Is the value of y?
Answer:
y= -12/5
Decimal form: -2.4
Step-by-step explanation:
Distribute the negative 3 on the left side
-3y-9=2y+3
Add 3y to both sides
-9=5y+3
Subtract 3 from both sides
-12=5y
Divide by 5 on both sides
y=-12/5 or -2.4

Answer:
(-4, 7)
Step-by-step explanation:
x is found on the x axis its -4
to find y you go up to where the point bvb is it is located at positive 7
Answer:
(-4,7)
Step-by-step explanation:
This is the answer because the x-axis is -4, and the y-axis is 7. If it was put in any other way it would be wrong.

In HIJ below, what is the value of y?
PLEASE ANSWER
Answer:
110
Step-by-step explanation:
The value of x in the given figure is y = 110. Hence option 3 is true.
Given that,
A triangle is shown in the image.
Apply the concept of the triangle that states,
The sum of two opposite interior angles in a triangle is equal to the measure of the exterior angle.
Hence we get;
y° + 20° = 130°
Subtract both sides by 20,
y = 130° - 20°°
y = 110°
Therefore, option 3 is true.

Does anyone know the differences and similarities between theorems and conjectures?
I searched on google but I didn’t understand! So in easy words please.. I’m sorry I’m dumb (;´༎ຶٹ༎ຶ`)
The difference between a theorem and a conjecture :-
Theorem :- Something which is true and can be proved .
I am giving a very simple example here .
Angle sum theorem :- sum of all angles in a triangle will be equal to 180° .
This is a theorem because every interior angle of a triangle will add up to 180° . It cannot change .
So , something that is definitely true and can be proved is a theorem .
Conjecture :- Something that is supposed to be true , but still hasn't been proved to be true .
Example :-
1a = 10
2a = 20
3a = 30
With this you can guess that 4a must be equal to 40 , but it can't be proved without using algebra .
Therefore , something which is likely to be true is a conjecture ( in maths ) .

What is the property that allows you to solve a polynomial by setting each 5p factor equal to zero? *
Example:
x^2 + 5x + 6 = 0
(x+3)(x+2) = 0 .... factor
x+3 = 0 or x+2 = 0 ... zero product property used here
x = -3 or x = -2 .... solve each equation for x
------
In general, the zero product property is that if A*B = 0, then either A = 0 or B = 0.
